Deformation during high pressure and pressure sequence hydroforming of tubes (original) (raw)

2001

Abstract

Hydroforming is a process used to manufacture tubular sections from circular tubes. Two systems for hydroforming are mainly used, high pressure hydroforming (HPH), and pressure sequence hydroforming (PSH). In this paper, an energy approach is used to calculate the compressive forces developed in the tube wall during deformation in PSH. The pressure required to prevent buckling of the tube wall is estimated based on a two dimensional buckling model. The differences in the mechanics of deformations between HPH and PSH are explained. The advantages and limitations of both systems are also summarized.
